Question Tags Questions
The rules for using question tags in negative statements are as follows:
1. If the main statement is negative (e.g., "He doesn't like coffee"), the question tag should be positive (e.g., "does he?").
2. If the main statement is positive (e.g., "She likes swimming"), the question tag should be negative (e.g., "doesn't she?").
3. The auxiliary verb used in the question tag should match the tense and person of the main statement (e.g., "He hasn't finished yet, has he?").
4. If there is no auxiliary verb in the main statement, we use the appropriate form of the verb "do" in the question tag (e.g., "They eat fish, don't they?").
5. In informal speech, the question tag may sometimes be formed using the contracted form of the auxiliary verb (e.g., "You aren't coming, are you?").
